Application filed August 9, 1915. Serial No. 44,520.

To all whom it may concern:

Be it known that I, DAVID PnrRI-PALMEno, a citizen of the United States, residing at Bridgeport, in the county of F airfield and State of Connecticut, have invented a certain new and useful Improvement in Matrix- Distributing Mechanism, of which the following is a full, clear, and exact description.

Certain forms of matrix distributing mechanism, for example, that which is shown and described in the Bellows Patent No. 921,065, are organized to push a line of matrices along distributing rails until the head matrix in the line is temporarily stopped in a true vertical position with its lower end over a gap or hole, and its upper end directly below a vertically .movable transfer blade. This transfer blade, as it comes down engages the top of the said head matrix and pushes it down, thereby transferring it from the distributing rails into the embrace of another support, as for example, a cage, as shown in said prior patent.

This invention is for the purpose of preventing the matrix-transferring movement of said blade, unless the said head matrix is in the proper position to be transferred; and this is desirable because, if the transfer blade moves down upon a matrix which by chance is not properly positioned below it, said matrix will be bent, and a bent matrix creates a lot of trouble in any line casting machine of which said distributing mechanism is a part. The invention as shown is particularly contrived for use as an addition to the distributing mechanism of the above mentioned prior patent, but obviously its use is not restricted to this particular mechanism.

The invention includes a dog which automatically seeks a position such as prevents the spring-induced downward movement of the transfer blade, and means whereby the head matrix in reaching the proper position will cause the withdrawal of said dog; and the invention consists in the combination of parts shown in the drawings and hereinafter described and definitely pointed out in the appended claims.

In the drawings, Figure 1 is a front elevation of so much of the distributing mechanism of a linotype machine of the character stated as is necessary for the understanding of the present invention, which is also shown; Fig. 2 is a sectional side view in the plane of line 22 on Fig. 3; Fig. 3 is a top plan view of the mechanism which forms the principal part of the present invention; Fig. 4 is an enlarged front view, partlysectioned, of the present invention; Fig. 5 is an enlarged front view of a part of said invention; Fig. 6 is a side view partly sectional of some of the parts of said invention; and Fig. 7 is a sectional plan view in the plane of line 7-7 on Fig. 4. g

Referring to the parts by reference characters, 10 represents the distributer rails by which a line of matrices M may be supported, and along which they may be moved by a follower 12 so as to carry the head (right hand) matrixgagainst the vertical left face of a stop member 14, and over a recess or gap 10 between the ends of the distributing rails, and said stop member. I

represents a vertically movable transfer blade whose function is to engage the top of the head matrix and push it down through said recess 10, and into the embrace of a cage 17. This transfer blade is connected with a vertically movable guided slide 21 which slide is engaged by one end of a lever 22. This lever is under theinfiuence of a spring 23 tending to rock it was to move said slide and consequently said transfer blade down; and a cam 24 engages said lever for the purpose of moving it and the slide and blade in the opposite direction.

All of the parts above described are parts which either in the precise form shown or some equivalent form are to be found in said prior patent.

The matrices M are of familiar form and each has a pair of cars m which respectively project forward and backward near its upper end, and another pair of ears m which respectively project forward and backward, near its lower end. While the matrices necessarily vary in thickness, the ears are preferably of the same thickness on all matrices,and preferably they are so arranged that the right hand aces of said ears are in the same vertical plane as the right hand face of the matrix. These lower ears are the parts of the matrices which rest and slide on the distributing rails 10.

In the vertical left face of this stop member 14 is a vertical groove 14. In this groove lies a pivoted dog 15 which is pivoted close to the lower end of said stop member,

and which extends upward in and beyond 19 said groove to a position such that its upper end may engage beneath a shoulder 21 which is rigidly fixed to said transfer blade; and a spring 15 acts to move the dog to this position (shown in Fig. 4) when possible. For convenience this stop shoulder 21* is a part of the slide 21 with which the transfer blade is connected.

Near its lower end, this pivoted dog 15 has a vertical slot 15 in which lies the middle part of a lever 16,-said lever being pivoted midway between its ends to said dog, by means of the pivot pin 16". The upper and lower ends of this lever are formed with short lugs 16, 16, which normally project to the left beyond the plane of the stop surface 14. When the head matrix is in the proper vertical position in contact with said stop surfaces, it will have engaged both the upper and lower lugs of said lever 16, and pushed both ends evenly to the right. In fact, said matrix comes in contact with both of said lugs before it reaches said stop surface, and by the time the matrix has come into contact with said stop surface it will have pushed equally against both lugs of thislever. Because of this even pressure the lever will not rock on its pivot, but, instead, the dog will be rocked on its pivot and will thereby be withdrawn from beneath the shoulder 21 connected with the transfer blade.

But if the head matrix in the line is not in a vertical position as it comes up to said stop member, this action will not take place. For example, if the top of the matrix is in advance of its bottom, said matrix will strike the upper lug of the lever 16, and by the time the upper end of the matrix comes against the stop surface it will have rocked said lever 16 upon its pivot; but this rocking movement does not cause any such movement of the dog 15 as will withdraw it from beneath the transfer blade. Therefore, the transfer blade can not come down.

So, again, if it is the lower end of the matrix in advance of the upper end, said lower end will by the time it has come against the stop member, have merely rocked the lower end of lever 16 to the right, and this will not have caused the releasing movement of the dog. In fact, the matrix must strike and apply equal pressure to both the upper and lower lugs of the lever 16 in order'that thereby there may be produced such a rocking movement of the dog 15 as will release the transfer slide to the action of its operating spring.

There are two matrix sustaining levers 25 lying in vertical recesses in the left face of the stop member 14, and pivoted near their upper ends thereto. Each has at its lower end a toe 25 which normally extends part way across the gap 10 and under the lower ears of the bee matrix, when the latter is pressing against near the stop which pivotally connects lever 16 with the dog 15 extends forwardly and backwardly through large holes 14 in the stop member 14 and into vertical slots 25 in these two levers. When, therefore, the matrix by the two lugs of the lever 16 rocks the dog 15 to an inoperative position, these levers will likewise be rocked so that their toes will be withdrawn from beneath the ears of the head matrix. Nothing now interferes with the downward movement of the transfer blade, or with the resulting downward movement of the head matrix through the gap 10; and said matrix is likewise in a position to be engaged and so moved by said transfer blade.

The above described mechanism prevents any matrix-transferring movement of the transfer blade unless the head matrix is in the right position to be transferred, and likewise it prevents the head matrix from falling through the recess 10 at any time except when the transfer blade has been released from restraint.

Having described my invention, I claim:

1. In matrix distributing mechanism, the combination of matrix supporting rails, a vertical stop member adjacent to but at a short distance beyond the ends of said rails, meansfor moving a line of matrices along said rails to carry the head matrix of said line against said stop member, and a springactuated vertically movable transfer blade, with a dog normally preventing the springinduced descent of said transfer blade, and means for withdrawing said dog,which means comprise a member which projects into the path of said matrix and is adapted to be moved thereby as said matrix moves toward and against said stop member.

2.
